🧬 Why do some women with tiny endometriosis lesions suffer severe pain, while others with larger ones barely notice?
A new study by the Sbarro Health Research Organization (SHRO) suggests the answer lies in the molecular “switches” that are flipped inside the tissue, not the size of the lesions themselves.
🔬 Led by Dr. Canio Martinelli, the research shows that endometriosis can activate any combination of six major biological pathways, many of which are also involved in cancer. These “switches” change how the disease behaves, spreads, and feels for each individual. “The pattern of switches, not the size of the lesions, drives how the disease looks and feels for each patient” - explains Dr. Martinelli, reproductive surgeon and first author of the study.
For SHRO President Dr. Antonio Giordano, these findings mark a turning point: “It’s a wake-up call. If we keep treating endometriosis as one disorder, we’ll keep seeing delayed diagnoses, now averaging seven years, and hit-or-miss therapies. Borrowing cancer’s precision-medicine playbook can change that.”
Prof. Alfredo Ercoli, Director of the Obstetrics and Gynecology Unit at the University Hospital of Messina and study co-author, adds: “Mapping these pathways lets surgeons plan with oncologic-level precision, predicting which lesions will invade deeply and which can be managed conservatively.”
🧪 The study also lays out a translational roadmap, from lab models to early clinical trials, to develop blood-based diagnostics and non-hormonal therapies.
From a fertility-surgery perspective, Dr. Andrea Vidali MD Endometriosis, Adenomyosis , Miscarriage and Dr. Francesco Di Chiara emphasize the benefits for personalized care: “Seeing endometriosis as several distinct conditions helps patients understand why treatments differ,” they explain. “Two patients both labelled ‘stage III’ often need very different approaches. Now we can point to the biology behind those differences.”
📍 From Naples to Philadelphia, SHRO is committed to transforming science into hope for women worldwide.
